UNI ED STATES PATENT MICHAEL STELL, or BRADFORD, ENGLAND.

Specification forming part of Letters Patent N0. 133,665, dated November 12, 1872.

To all whom it may concern.-

Be it known that I, MICHAEL STELL, of Bradford, in the county of York, England, worsted spinner, have invented certain improvements in machinery or apparatus for spinning, twisting, or doubling worsted, woolen, cotton, silk or other fibrous substances, of which the following is a specification:

Nature and Objects of the Invention.

' one or two feathers or ribs on the side thereof and the bobbins are formed with grooves or slots to fit the tubes, so as to slide freely thereon and be driven thereby. The bobbins are supported upon and moved up and down on the tubes by the ordinary lifter-plate, and driven by pins in the whirls entering notches or holes in the tubes, or vice versa; or, instead of pins, as aforesaid, I may form a tapered socket or recess in the whirl, and a cone or conical part on the foot of the tube fitting into the socket, or vice versa; second- 1y, instead of the dead spindles or studs being constructed with fixed collars or shoulders, as heretofore in use, I construct them straight and apply a loose collar thereto on which is a split boss to fit and be fixed in the spindle-rail, by which means the said spindle may readily be adjusted without injury thereto. The third part of my invention relates to the rollers of twisting-frames, and consists in having each top roller or pressing-roller mounted' on a lever, the said lever being hinged on a stud-pin in suitable position for the said roller to be in contact with the plain bottom rollerwhen twisting,with an adjustable weight applied on the opposite end, adjusted so as to cause the top roller to rise out of contact with the bottom roller when one of the ends or threads break, such top roller being kept in contact with the bottom roller only, while more than one thread of single yarn is in continuity or unbroken, the contact depending upon the pressure of the yarn on the said lever.

The following is a full and complete specification of this invention, reference being had to the three sheets of drawing accompanying the same.

Sheet 1 is an end elevation of a spinningframe or machine for spinning and twisting worsted yarns; Sheet 2 is a front elevation; and Sheet 3 contains a series of figures, being details of the same.

Similar letters refer to the same parts of the apparatus, as shown in the several sheets and figures.

The first part, relating to the mounting and driving of the bobbins or spools, is shown as applied in the Sheets 1 and 2, and in detail in Sheet 3, where Figure 1 is an elevation and, Fig. 2 is a vertical section of the same.

A is an ordinary cap, supported on the top of a spindle or rather a stud, B, which is fixed in the rail 0 by means and in manner as here inafter explained. D is the whirl loose on the stud driven by a band in the usual way; and E is the tube, also loose on the stud, but attached to the whirl by pins a which enter notches or holes in the flange E of the tube, shown in plan at Fig. 3. Or, instead of pins and notches, the whirl may be recessed and the'tube formed conical, as shown in section at Fig. 4. F is the bobbin or spool, grooved so as to fit upon ribs or feathers e on the tube, by which the said bobbin or spool is driven. An end view of the said spool is shown at Fig. 5. The spool-bobbin F is placed with its flange uppermost, and thus reversed or contrary to the usual method of placing the same on the tube; and this arrangement is for the purpose of commencing to wind the yarn at the top end of the spool, so that, as it becomes wound thereon, it will be carried within the cap, and thereby protected from the irritating influence of the atmosphere. It will be observed that in placing and using spool-bobbins with the flange uppermost, ribs or their equivalents on the tubes are required to drive the said spools, and that this arrangement is equally applicable for twisting or doubling as for spinning on the cap-frame.

The second part is also shown at Figs. 1

and 2, Sheet 3, where it will be seen that the dead spindle or stud B is parallel throughout its length and is fitted into a bush or boss-H, the top part forming a collar recessed to receive a lubricating washer, I, for the whirl to rest upon. This boss is split longitudinally for a part of its length and is fixed in the rail 0 by set-screw J, which also fastens the stud therein; and, in order to adjust the stud in proper position, another set-screw, K, is inserted into the boss at the bottom end of the stud which, when adjusted, is made fast by a locknut, L. It will be seen that no collars are required to be formed on these dead spindles or studs 5 consequently such studs can be made very cheap, and, by this method of fixing them, they are equally secure in their position and less liable to injury by fixing than by the old method of fixing studs. M are the guards, fixed in metal brackets N, which are screwed to the beam or board 1?. These guards are,

by preference, made of sheet-steel so that they will be less liable to get out of proper position, and on which a smoother surface may be produced than by using softer metals; but tin or other softer metals may be used for this purpose and fixed in the brackets, as aforesaid.

The third part of my invention, relating to twisting-frames, is also shown on Sheets 1 and 2 of the drawing, where R are the ordinary bottom drawing-rollers and S the top rollers, which latter are mounted on studs carried by levers T, one end of which is formed into a tweezle or a guide-eye, U, and the other having an adjustable balance-weight, W, attached thereto. A lever and top roller are also shown in Sheet 3 of the drawing in detail. Yarn to be twisted or doubled is placed upon the bobbins X on studs on the creel-board in the usual manner, the yarn 3 passing in between the drawing-rollers and through the eyes of the lovers T, thence over the caps to the spools. It will be observed that these levers are so constructed, arranged, and adjusted that, by means of the adjustable weights, the rollers are only kept in contact by the pressure of the continuous-passing yarns or threads, and the weights can be so nicely adjusted that if one of the yarns or threads breaks the remaining one will not be sufficiently strong to keep the top roller in close contact with the bottom one, so that the rollers will cease to draw the yarns or threads forward; consequently, it one of two yarns or threads breaks the other will also be broken, and thereby prevent making bad twist or making single yarn when it ought to be double.

Claims.

1. The whirls D, runningloosely on the studs B under the lifter-rail and provided with pins a or a hollow cone, in combination with the tubes E provided with holes, notches, or cones, the said tubes having ribs or pins 0 to fit into grooves formed in the bobbins or spools F, as described.

2. The combination of the parallel studs B and split bosses H, which form collars for fixing the studs in the rail, with the means of adjusting the said studs, as described.

3. The weighted-levervT, carrying the top rollers S and tweezles U, combined with the bottom rollers R, and constructed and ar ranged to operate substantially in the manner and for the purpose specified.
